Abstract.
In this note, we examine the structure of closed ideals of a quasianalytic weighted Beurling algebra \(\cal {A}\). This algebra is contained in \({\cal C}^\infty (\mit\Gamma)\) and contains the set \(A^\infty (D)\). Like in a previous article (see [6]), we use division properties and we give a characterization of closed ideals I such that \(I\cap A^\infty\! \ne \{ 0\} \). Then, we use a factorization property proved in [2], which allows us to describe all the closed ideals of \(\cal {A}\).
